DETAILED DESCRIPTION

[0023] Example 1

[0024] like Figures 1-4As shown, the asphalt mixture wheel forming machine proposed in the present invention includes a storage barrel 1, a drive assembly A4, a wheel rolling mechanism, and a grinding assembly. A storage tank 101 is provided within the storage barrel 1, and an annular groove 102 is provided at the bottom of the storage barrel 1 and communicates with the storage tank 101. A discharge hole 103 is provided at the bottom of the storage barrel 1, located at the bottom of the annular groove 102 and communicates with the storage tank 1. A cover plate 2 is provided at the bottom of the storage barrel 1 to close the discharge hole 103. A hinge is provided on one side of the cover plate 2, which is rotatably connected to the bottom of the storage barrel 1 via the hinge. The drive assembly A4 is connected to the storage barrel 1 and includes a latch 41 and a hydraulic cylinder A42. A material guide pipe 3 is provided at the bottom of the storage barrel 1, sleeved outside the discharge hole 103 and communicated with the discharge hole 103. The material guide pipe 3 has two symmetrical sockets 301. A latch 41 is inserted into the storage barrel 1 along the exterior of the material guide tube 3, passing through a receptacle 301 on one side and extending into a receptacle 301 on the other side. The latch 41 is in contact with and slidably connected to the lower surface of the cover plate 2. A hydraulic cylinder A42 is connected to the outer wall of the material guide tube 3. The push rod of the hydraulic cylinder A42 is connected to the end of the latch 41 extending outside the material guide tube 3, thereby controlling the opening and closing of the cover plate 2. A wheel-rolling mechanism is located within and connected to the storage barrel 1 and comprises a turntable 7, a roller 8, a shovel 9, and a drive assembly B10. The turntable 7 is located within the annular groove 102 and is rotatably connected to the upper surface of the bottom plate of the storage barrel 1. A rotating shaft is provided on the turntable 7 for rotation perpendicular to its radial direction. Two rollers 8 are connected to corresponding ends of the shaft. The rollers 8 are located within the annular groove 102 and roll along the bottom of the annular groove 102 around the axis of the turntable 7. The shovel blade 9 is connected to the turntable 7 and slides against the inner wall of the annular groove 102. The drive assembly B10 comprises a reducer, coupling A, coupling B, and a motor. A drive shaft is located at the bottom of the turntable 7, extending through the bottom of the storage tank 1 and rotatably connected thereto. The reducer is connected to the storage tank 1, with the reducer output connected to the drive shaft via coupling A, and the motor output connected to the reducer input via coupling B. Drive assembly B10 drives the turntable 7 in rotation. The wheel milling mechanism cyclically mills the raw material when in operation. The grinding assembly comprises a grinding sleeve 5 and a grinder 11. The grinding sleeve 5 is coaxially located within the storage tank 101. The grinder 11 is coaxially located on the turntable 7. The curved outer wall of the grinder 1 is provided with several tooth grooves 111, and the diameter of the lower surface of the grinder 11 is no less than the outer diameter of the turntable 7. The grinding assembly and the wheel milling mechanism are linked to each other to grind and comminute the raw material added to the storage tank 1 when the wheel milling mechanism is in operation.

[0025] In this embodiment, the raw materials are added to the storage barrel 1 through the opening thereof, and the motor is started. The motor cooperates with the reducer to drive the turntable 7 to rotate, thereby driving the grinder 11 to rotate. The grinder 11 cooperates with the grinding sleeve 5 to grind and crush the large particles in the raw materials, and then the raw materials fall into the annular groove 102. When the turntable 7 rotates, the grinding wheel 8 follows the turntable 7 and rotates around the axis of the turntable 7. While the grinding wheel 8 revolves around the turntable 7, due to the friction between it and the bottom of the annular groove 102, it rotates on its own, thereby crushing the raw materials. At the same time, the shovel plate 9 turns the raw materials in the annular groove 102, promoting the mixing of the raw materials while effectively preventing the raw materials in the annular groove 102 from adhering to the inner wall of the barrel. After the raw materials are formed, the hydraulic cylinder A42 is started, and the hydraulic cylinder A42 drives the latch 41 to slide. The latch 41 no longer limits the cover plate 2, and the cover plate 2 automatically flips downward under the action of gravity, and the raw materials are discharged along the discharge hole 103. During the discharge process, the shovel plate 8 rotates in the opposite direction and pushes the mixed raw materials to the discharge hole 103, so that all the raw materials in the storage barrel 1 are discharged, and the scraper can also be used to clean the inner wall of the storage barrel 1 to prevent it from hanging on the wall. After the discharge is completed, the hydraulic cylinder A42 pulls the latch to slide, and the latch gradually pushes the cover plate 2 to flip it over and reset it.

[0027] like Figure 1-Figure 3 As shown, the asphalt mixture wheel rolling machine proposed by the utility model, compared with the embodiment 1, is provided with a fixed plate on the storage barrel 1, and a hydraulic cylinder B6 is provided on the fixed plate. The push rod of the hydraulic cylinder B6 is connected to the grinding sleeve 5, and the top end of the grinder 11 is coaxially connected to the reinforcing shaft 12, which passes through the fixed plate and is rotatably connected thereto.

[0028] In this embodiment, the hydraulic cylinder B6 is used to drive the grinding sleeve 5 to rise and fall, thereby changing the distance between the inner wall of the grinding sleeve 5 and the outer wall of the grinder 11, thereby achieving the purpose of adjusting the particle size of the initial processing of the raw material.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
